Torsion bar backing out??

That picture charger70 posted shows a torsion bar adjustment bolt and swivel that you will find nestled between the walls of the lower control arms (underneath). Turning them will adjust your ride height. You can get the weight off the front end with a jack to make it easier to turn the bolts.

You should really consider purchasing a Factory Service Manual, CD of the Manual distributed by Detroit Iron Informations Systems, or at the least, a Haynes Repair Manual 30025 or 30050. The procedure is explained there.
